The narrative elements that are similar in the stories of Deucalion and Atrahasis include a great flood, a divine warning to a select individual about the impending disaster, and the survival of that individual by constructing a vessel. These elements are commonly found in flood narratives across various cultures. In both stories, there is also a theme of rebirth or renewal of humanity following the destruction.
